String the car. At ride height, use 4 jack stands, and some kite string. Tie the string between two jack stands, along both sides of the car. Move the jack stands in such a way as to make the string tight. The trick is measuring. You want the string to be an equal distance from the forward face of the rear wheel, and the rearward face of the rear wheel. Don't measure to the tire, use the wheel. Once the string is perfectly parallel with the rear wheel, measure the front, and adjust accordingly. Set the parking break, before you jack the front end up, to adjust your toe, to help the car stay exactly where it was. Once it's back at ride height, re-measure the rear, to make sure your good. DO NOT bump the jack stands during this entire process, once they are set. Move carefully around them.

This is an old school way of setting toe, but it works. For a lot of chassis guys/car builders, strings, and plumb bobs are the most used tools in the shop.
I've done this with both strings, and lasers.
